Boots



UNITED STATES PATENT OFFICE.

FREDERICK GLOSS, OF NEW HAVEN, CONNECTICUT.

BOOTS, &G.

.To (tZZ whom it may concern.-

Be it known that I, FREDERICK GLoss, of the city and county of NewHaven, and State of Connecticut, have invented a new and usefulImprovement in Attaching the Soles to the Uppers of Boots, Ste.; and Ido hereby declare that tne following'is a full, clear, and exactdescription ofthe construction, character, and operation of the same,reference being had to the accompanying draw-ings, which make part ofthis specification, in which- Figure l is a perspective view of a bootmade complete, showing the whole appearalice of the sole and upper, withno appearance ot' stitches, channeling, or similar means. Fig. 2 is aperspective view of a portion of the work as viewed from the inner side,showing the position of the stitches on the inner side of the innersole. Fig. Bis a cross-sec tion of the boot enlarged, showing the stitchas closely drawn at the left-hand and as left considerably loose, toshow the nature of the stitch, which is sewed from outside to insidethrough a small pellicle or sliver of the upper corner of the outersole, the upper leather, and the. inner sole.

My improvement consists in sewing the soles ot boots or shoes (withproper machin-- ery, which will be explained when a proper model isprepared) to the uppers from outside to inside of the article, and yetleaving the outer sole to be worn oi' to the last pellicle or fragmentwhich can hang together before the wear can come in contact with thestitches which secure the outer sole to the boot, (and the same may bepracticed for double soles, Sac., it' desired.) This obviates aprominentobjection to machines, because in the common way of sewing by machinerythe holes are made so large that as soon as the stitches are wornoit thesoles will drop oli' by slight jarring; but when, as in mine, thestitches can not receive any wear, the soles must remain iirmly andsecure in their places until the soles are entirely worn out, as`nothing can affect them. I split up a small portion or pellicle of theupper corner of the outer sole allround the foot, as shown at a b, Fig.3,

and also at a., Fig. 2. I last the uppers over the inner sole in theordinary way, so that when I put on the outer sole the edge of the upperwill be between the inner soie and the split-up pellicle -or sliver a b,the whole, as indicated in Fig. 3. Ill/'hen the parts (soles and uppers)are thus fitted and arranged, l put the machine in motion, when thesewing will be accomplished (by the proper functions of my machine) fromthe inside to the outside through the inner sole, c d., uppers f g, andthrough the pellet or sliver a b, which may rst'appear open, as at b d,Fig. 3, but which the machine will immediately close, as represented 1ncross-section at a, Fig. and inper-AA spective at a, Fig. 2, where onestitch, e, is un'- covered and the same character i'or the inside ot'the whole length of Fig. 2. In the outer portion of this stitch-thatis,atc b--thepellet or sliver is drawn up so far that no part of thethreadcomes down as low as the upper surface of the outer sole, as isrendered perfectly apparent at a, Figs. 2 and 3, and when the boot isfinished no stitch will be seen about its sole.

I can in,this`way and by these means make as durable or serviceable aboot by machinery as can be made by hand, for neither can everI'ailuntil after the stitches wear ofi,

and by my method it is impossible that the stitches should wear at alluntil the whole of the outer sole is worn off, as before shown.

WhatI claim as my invention, anddesire to secure by Letters Patent, 1s-.

Sewing (by machinery) the soles to vthe uppers of boots and shoes,substantially as herein described.

F. GLOSS.
